Good or bad, no one is going to beat Trump except Biden. I'll take the last 4 years we've had, where he's had times that he seems out if it, but the country is doing a lot better and doesn't seem like we are at each other's throats. If he dies the day before election, I'll vote for his corpse.
If I'm not mistaken, Biden could add seats if he wanted to, so could any president. I think no one wants to do it because then the other party would add more as well.
Pussies don't like dicks, because pussies get fucked by dicks. But dicks also fuck assholes: assholes that just want to shit on everything.
